It seems like the driver should have sufficient information based on the
pixmap it is passed -- pass one of the scanout pixmaps and it should
know to copy bits in the other scanout pixmaps.
The goal is to eliminate all protocol objects from the driver interface,
it seems like the simplest way to remove the protocol Window objects
From the driver interface is to expose only pixmaps.
